Filed: 1970-12-21
Abstract: 1303899 Implantable artificial hearts COMMISSARIAT A L'ENERGIE ATOMIQUE 21 Dec 1970 [31 Dec 1969 12 Aug 1970] 60574/70 Heading A5R [Also in Division Fl] An implantable artificial heart comprises a hydraulic device for pumping blood which is actuated by a motor having a linear-displacement piston 48, Fig. 2, a relaxation mechanism having a member 62 fixed to a driving member 30 of the hydraulic device and a member 60 fixed to piston 48 with a compressible elastic member, such as spring 64, therebetween, and abutments 66, 68 limiting separation of members 60 and 62 so that during the working stroke of piston 48 (arrow f) the latter initially rapidly compresses spring 64 with practically no movement of member 30 until at the end of its working stroke piston 48 is temporarily locked in position by a catch 70, 72 whilst the spring 64 expands to move the member 30 to pump blood, a member 74 unlocking the catch when abutments 66, 68 act to stop expansion of the spring, maximum and minimum compression of the spring 64 producing a blood pressure corresponding to the pressure in a natural heart at the beginning and end, respectively, of the systole phase. Cardiac modules 10D, 10G, 12D, 12G, Fig. 1, corresponding to right and left auricles and right and left ventricles respectively each have a chamber 24 for blood separated by a diaphragm 20 from a chamber 22 for intermediate pressure-transmitting liquid, the blood chambers communicating with a duct 16 connected between the pulmonary vein and the aorta or with a duct 18 connected between the vena cava and pulmonary artery. Blood is drawn into modules 10D, G and pushed out of modules 12D, G during the expansion of spring 64 by movement in the direction of arrow f of a piston 28 defining one wall of cylindrical chambers 32, 36 and of an annular chamber 34 containing the intermediate liquid. Return of pistons 28 and 48 is effected by natural body blood-pressure forces and by magnets 78, Fig. 2, acting on plates 76 and assisted, if required, by a spring. At the start of its working stroke, piston 48 is in a position opening a spring-loaded valve 46 allowing admission of vapour from a boiler 42, having a plutonium 238 heat-source 40, into chamber 44 to move piston 48. At the end of the working stroke piston 48 opens ports 50 to discharge vapour from chamber 44, such vapour condensing either in a capillary condenser 54 or on the walls of casing 52 from which it is led by capillarity to condenser 54. Condensed working fluid returns to boiler 42 via pipes 56 and non-return valves 57 by means of a pump comprising a piston 80 fixed to member 30 and moving in a cylinder-forming member 82 fixed to chamber 44. The motor comprising members 40, 42, 44, 46, 48, 54, 80 and 82 may work on the Rankine or Hirn cycle using water as the working fluid.

Abstract: 662,382. Recording-apparatus. BRITISH CELANESE, Ltd. July 29, 1949 [July 29, 1948], No. 20002/49. Class 106 (iv). [Also in Group VIII] Apparatus for recording the number of times a machine stops comprises a holder for a record medium, marker means for connection to the machine and for actuation by the starting and stopping thereof, said means being adapted to make a mark on the record medium for each time the machine is started and to lock said medium in the recorder until the machine is stopped, and means for moving the marker relatively to the record medium each time the record medium is unlocked so that the marker makes its next mark in a different place. In the embodiment described, the machine cannot be operated until a card 24 has been inserted in the recorder to displace a roller 38 coupled to a switch arm 37, this displacement closing a switch 36 permitting the driving motor of the machine to be energized. Upon starting the said motor, a solenoid coil 44 is energized to draw in a plunger 46 and drive a pin 84 through the card 24 by means of a pivoted lever 86 and a rotatable carriage 74 slidably mounted on a shaft 59. This movement of the plunger 46 locks the card 24 in the recorder by means of the pin 84 whilst the machine is running, and also rotates a rod 93 upwards against a spring pawl 66 to move a hook 67 at the end of the pawl 66 past one of the teeth 68 of a wheel 62 connected to the carriage 74. When the driving motor is stopped, the solenoid coil 44 is no longer excited and the spring pawl 66 moves the arm 93 downwards to withdraw the pin 84 from the card 24 and the plunger 46 from the coil 44. The pawl 66 is of such a length that it does not engage the wheel 65 until the pin 84 is clear of the card 24, the pawl 66 then engaging the wheel 62 to turn it and also the carriage 74 and the pin 84 about the shaft 59. Every time the machine is operated, therefore, the pin 84 is driven through a fresh point on the card 24. Specifications 541,729, [Group VIII], 609,499, [Group IX], and 650,210, [Group XL (b)], are referred to.

Title: Two-terminal semiconductor microwave device
IPC: H01L29/41
Filed: 1978-08-04
Abstract: This disclosure relates to two- terminal solid state microwave devices, such as transferred electron and avalanche effect devices, comprising a high-conductivity semiconductor substrate 1 formed over at least a part of one major surface with an active layer 4 of semiconductor material, a first contact 2 providing electrical contact with the active layer to define the active region of the device, and a second contact 3 on the same side of the substrate, providing a relatively low impedance ohmic contact to the substrate in operation of the device at the operating bias current for the active region. To simplify fabrication, both contacts may have substantially identical structures with the second contact also overlying the active layer. In the case of transferred electron devices as shown, the area of the second contact is then made greater than the first so that it is biased below threshold at the operating bias current for the active region; while in the case of avalanche effect devices having rectifying semiconductor junction contacts, only the first contact is reverse biased in operation, the second contact being forward biased to behave as an ohmic contact to the substrate. Methods of fabricating such devices are also disclosed. <IMAGE>

Patent GB-2036680-A (GB)
Title: Conveying goods through processing machines
IPC: B65B35/26
Filed: 1979-10-03
Abstract: A plate 5 rotates step-by-step, bringing a plurality of seats 6 in succession over an elevator member 21. Each seat accommodates a product P and when each seat stops over the elevator member 21 the member 21 rises to grip the product and a wrapper Z against a counter elevator 22. The elevator member and the counter-elevator then rise together, the elevator member passing through the seat 6, to transfer the product to a wrapping station S. To increase the production rate of the machine, the plates does not wait until the member 21 has withdrawn from the seat 6 before the plate carries out its next increment of rotation. Instead the elevator member 21 moves with the seat 6 as the plate 5 rotates, carried on a slide 37 movable along rods 37. Thus withdrawal of the elevator member can take place while the plate 5 is rotating. <IMAGE>

Title: Glassplastic laminate and method and device for its production
IPC: B29C63/00
Filed: 1978-09-29
Abstract: Laminate of glass and plastic and a method and a device for producing the same. To obtain an impact resistant laminate the glass in the laminate is compressed over its entire cross section by means of the plastic which is in a state of elastic tensile strain. The forces between the glass and the plastic are transferred by means of a layer of non cold creeping adhesive between them. The laminate is prepared by joining the glass to the plastic with a non cold creeping adhesive whereby the joint is kept free from shear forces during the entire gluing and curing of the adhesive whereafter the glass, after completed curing of the adhesive, is subjected to compression by means of contracting forces from the plastic. The contracting forces in the plastic can e.g. be obtained by mechanical stretching before or during the gluing or by gluing at an elevated temperature. A device for producing the laminate comprises a frame (3) for supporting the plastic material (4) and means (2 or 6) for applying a distributed bending force essentially perpendicular to the plastic material and between the points of support.
